Chicago police are investigating after a man was shot multiple times as he left a popular 24-hour restaurant in the South Loop overnight.

At about 2:58 a.m., a 42-year-old man was leaving the White Palace Grill in the 1100 block of South Canal Street when an unknown man fired shots and then fled the scene, police said. The victim was hit multiple times and taken to a nearby hospital in good condition, police added.

As of 5:30 a.m., the scene was still busy, with several officers on duty and the area outside the restaurant cordoned off with yellow crime scene tape. NBC 5 traffic reporter Kye Martin reported that Roosevelt Road between Clinton and Canal Streets was closed while the investigation continued.

Witnesses said some people who were in town for the Democratic National Convention were in the restaurant at the time of the shooting. Photos and videos from the scene show several people wearing DNC lanyards standing on the sidewalk near the eatery.

“Suddenly we heard gunshots and they were very close,” said Javier Mabrey, a witness and DNC attendee. “Half the people in the restaurant were from the DNC.”

During his speech, Mabrey of Colorado wore a button that read “Freedom from Gun Violence” on his jacket.

“This is the reality that people are facing across the country,” Mabrey said. “This is not just a Chicago problem. This is a Colorado problem. This is a Nebraska problem, this is a Washington state problem, this is an Oregon problem. This is an American problem. This is an American problem.”

The restaurant is located about two miles from McCormick Place, one of two venues in Chicago that have hosted DNC events.

The shooting occurred hours after Vice President and Democratic presidential candidate Kamala Harris spoke at the United Center on the fourth and final night of the DNC in Chicago.

According to police, no one was arrested; detectives are investigating.
